To be clear, though, is this a grandparents' rights issue, or just your W being really really stubborn and refusing to compromise?
Hope you can make the logistics work, that is really frustrating.
I thought grandparents' rights would come up in a situation where, say, I don't let my parents see my kids (which... I actually don't right now, which is a whole other story...) and then the grandparents' have to petition the court for visitation, etc.
